Looking to buy an iPad mini from the US and have a friend post it over to avoid Apple's disgusting conversion rate. On the store it says: "iPad mini with Wi-Fi + Cellular can roam worldwide on GSM/UMTS networks. In countries without compatible LTE networks, iPad mini will operate on GSM network technologies such as HSPA+ and DC-HSDPA. When you travel internationally, you can use a nano-SIM card from a local carrier." Does that mean that when outside the US, the iPad mini is effectively unlocked and will take any sim card, and only in the US are you tied to one carrier?
